SELF-ADJUSTING H EAD-GATE.

SPECIFICATION forming part of Letters Patent No. 367,459, dated August2, 1887.

Application filed November 1, 188. Serial No. 57,762. (No model.)

To all whom it may concern.-

Be it known that I J AMES SrIcKLE, a citizen of the United States,residing at Denver, in the county of Arapahoe and State of Colorado,have invented certain new and useful Improvementsin Self-AdjustingHeadGates; and I do declare the following to be a full, clear, and exactdescription of theinvention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

My invention relates to selfadjusting headgates for regulating the flowof water from irrigating-ditches; and the object of my improvements isto provide a cheap and effective self-adjusting device which will at alltimes deliver the same amount of water during a given period Of time,regardless of the head in the ditch. I attain this object by themechanism illustrated in the accompanying drawings, in which Figure l isa side view of the entire device; Fig. 2, a top view of the float-boxand tailgate; Fig. 3, an end view of the head-gateand its attachments;Fig. 4, an end view of the tail-gate and its attachments and thefloat=box.

Similar letters refer to similar parts throughout the several views.

a is the frame of the device.

a is a spout which carries the water from the ditch through embankment Aand delivers it through the outlet on the right of Fig. 1, as shown bythe arrows. This outlet 0 is made of a proper size to deliver a givenamount of water in a given time under a certain pressure or head. Theopening din the ditch orstream, being much larger, admits enough waterto raise the level in box e, so that it will overflow from its top,which is open. The side of c, which also forms a partition betweenitself and float-boXf, is cut away, so that when the water reaches acertain point in c it will run over the partition 6' into thefioat-boxf. Sliding screen 9 has a wide frame, with wire-nettingcovering the central square opening, 9, and is placed in'slides g 9 nextthe partition 0'. The netting g is to prevent floating sticks and thelike from entering the float-box, and the wide frame operates as a gate,which, to-

I gether with the partition, varies the height to which the water mustrise in box 6 before it can flow into the fioat-boxf. In the lowerportion of the float-box are holes h, Flg. 4,

from which the water is continually flowing when there is any in the boxf. The headgate i is formed of any suitable materlal and held inposition by arms j, the outer ends of which are pivoted to the gate i atj, and the inner ends pivoted to the frame atj". To the upper end of thehead-gator is fastened a cord, k, at t". The cord is is then passed Oyerthe pulley-wheels Z and Z and fastened at k to the top of the standardm, the lower end of whlch is securely fastened to the float n at n. Inthe top of the standard, a little below the end, is placed apulley-wheel, Z At i is attached to the head-gate a cord, 0, which 1spassed under the wheel Z" and lfiover Z and one end fastened at 0 to theframe. 12 and q are slides used to shut off the passage of water throughthe device. r is a box to guard the cord 0 from the embankment. Inoperating,asufficient amount of water, by the slide 1), is turned on toraise the surface above the outlet 0, until the desired pressure isobtained, when the cord 7c is adjusted in such a manner that when thefloat n is at the top of the float-box f, as shown by dotted lines 6,the head-gate t is in the pos1- tion shown by dotted lines f, and as thesurface of the water lowers in the float-box f the headgatei is raisedin-proportionto the low ering of the float, and, as the float 1s ra sedby the action of the water in f, it also raises the standard m, whichpulls the cord 0, which in turn pulls down the gate 1', which shuts offthe water as it descends. Vhen from any cause the water surface islowered in the stream or ditch, so that the water ceases to flow intothe float-box, the water in the float-box runs out of the holes h andlets the float n down, which opens the gate 6, and as soon as the waterin the ditch rises and sufficient runs in to raise the surface so thatit will run over the partition 6, the float will raise and lower thegate 1 t. Thus it will be seen that the pressure in 6 will be keptuniform regardless of the height of water above the opening d, and,aslthe flow through the outlet 0 is regulated by the pressure or head ofwater in c, it will be uniform and always discharge a given amount ofwater duringa given space of time. I do not confine IOO myself to thisexact hanging and directing the cords 7c and 0; but

\Vhat I do claim, and desire to secure by Letters Patent, is

1. In combination with a spout or waterway, a, a gate, 2', arranged tobe moved to open and close the inlet to said spout or way, a box havingan outlet arranged to receive water from said spout, a float in saidbox, a cord, 0, connected with the gated and to a suitable point nearthe float o2, suitable pulleys over which this cord is passed, and thecord 7r, also connected with the gate i and with the float n, andsuitable pulleys over which this cord is passed, whereby when the waterrises and falls in the float-box the gate "5 will be oper-
